Answer:
7/10 pi (radians)
Step-by-step explanation:
The formula for sector area is (angle * r^2)/2
140pi = angle*r^2/2
multiply both sides by 2
280pi = angle * r^2
r = 20 cm (substitute)
280pi = angle * (20)^2
280pi = angle * 400
Divide both sides by 400
7/10 pi = angle
3x + 6 + x + 2 = 180
4x = 180 - 8
4x = 172
x = 43
A = 3x + 6 = 3×43 + 6 = 129 + 6 = 135
make a line going straight from (0,0) to (2,2) and so on and the other line starts at (0,0) and go to (1,1) and follow along the other line
Answer:
Only Once
Step-by-step explanation:
Because 12 is one less than 13, we can fit the number in only ONCE because if we were to do it twice 24 exceeds over 13.
